Answer:
Organisms that can make the food using simple substances are called autotrophs.
What is the crest and trough of a wave?
Answer:
Explanation:
A crest point on a wave is the maximum value of upward displacement within a cycle. A crest is a point on a surface wave where the displacement of the medium is at a maximum. A trough is the opposite of a crest, so the minimum or lowest point in a cycle. When the crests and troughs of two sine waves of equal amplitude and frequency intersect or collide, while being in phase with each other, the result is called constructive interference and the magnitudes double (above and below the line). When in antiphase – 180° out of phase – the result is destructive interference: the resulting wave is the undisturbed line having zero amplitude.
Draw and use algebra tiles to solve the equation. 2x + 3 = 5 x =
Answer:
1 is the correct answer:)
Subtract
3
33
from both sides of the equation
2+3=5
Simplify
Subtract
5
5x5x
from both sides of the equation
Simplify
Divide both sides of the equation by the same term
Simplify
than you will have 1.

Use the reading below to answer the question.
The layer of soil above the permafrost is too shallow for plants with deep roots to live. Grasses and shrubs can survive there because they have shallow roots. A sheet of mosses and lichens grows beneath these plants. When the soil above the permafrost thaws, the soil becomes muddy. Muddy soil is an excellent place for insects, such as mosquitoes, to lay eggs. Many birds spend the summer in the tundra to feed on these insects.
Based on the passage, what is one reason for the lack of trees in the tundra?
A.
soil depth
B.
amount of rainfall
C.
temperature range
D.
amount of sunlight
Answer: I think it is amount of rainfall

Read the article excerpt below then answer the question.
Why is hydrogen a “cleaner” fuel source than gasoline?
Compared to the carbon dioxide that is produced when we burn gasoline, ethanol, and other carbon-containing fuels, the water produced by burning hydrogen has a less harmful effect on Earth’s climate. If we can power our cars with hydrogen without producing carbon dioxide, then why don’t more vehicles use hydrogen fuel? Unfortunately, the technology needed to use hydrogen as a fuel is expensive, and storing hydrogen fuel can be difficult. Also, the most common way of getting pure hydrogen is by separating it from substances that contain carbon—so although burning hydrogen fuel does less harm to Earth’s climate than burning carbon-containing fuels, the production of hydrogen fuel is still a problem for scientists trying to reduce climate change.
Why is hydrogen a “cleaner” fuel source than gasoline?
hydrogen is natural created and in the air already, gas is a fossil fuel and is killing the Ozone layer. carbon dioxide is a poison and can really harm us and the world.

What are some of the reasons climate change is so bad for communities of color? HELP PLSSSSSSSS
Answer:
Here is a link that will explain more specifically.
https://www.greenamerica.org/climate-justice-all/people-color-are-front-lines-climate-crisis
Explanation:
The United Nations International Panel on Climate Change’s (IPCC) 2013 climate change science report states with “90 to 99 percent certainty” that more frequent and more severe weather events like droughts, intense heat waves, and “more frequent/ intense heavy rainfall events” are a consequence of the climate crisis. And it is communities of color that are bearing the brunt of those events, say many experts.
Other communities of color are also feeling the heat. In California, for example, record heat waves and droughts are affecting Latino communities hardest throughout the state, says Mario Santoyo of the California Latino Water Coalition.
As state farmers see their fruit and vegetable crops shrink from lack of water, it’s the state’s majority-Latino farmworkers who are struggling most as a result, as they scramble to get enough hours picking crops to earn a livable wage.
What measures the energy of a wave?
Answer:
ampiltude
Explanation:
Amplitude means a measure of the amount of energy in a wave. Notice in the drawing below how the amplitude measures the height a wave is going above or below the resting position of the wave.
anyone please help? !!!DUE IN 10 MINS!!! PICKING BRAINLIEST TO WHOEVER IS RIGHT!!!
Answer:
In many areas, rain or snowmelt on seasonally frozen soil is the single leading cause of severe runoff and erosion events. As soils freeze, ice blocks the soil pores, greatly diminishing the permeability of the soil. This is aggravated by the tendency of water to migrate to the freezing front, causing elevated ice content and frost heave.

If an object is placed in water and has a density of 1.9 g/ml will the object float or sink?
Answer:
float
Explanation:
since everything that have a density more than 1g/l (not g/ml) will sink and less than that will float
then 1.9g/ml < 1g/l
Answer:
it would sink
Explanation: it would sink because the density of water is 0.997 m/ml and 1.9 is more then that

What do the key differences between RNA and DNA mean for the spread of these types of viruses?
Answer:
DNA viruses contain usually double‐stranded DNA (dsDNA) and rarely single‐stranded DNA (ssDNA). These viruses replicate using DNA‐dependent DNA polymerase. ... Compared to DNA virus genomes, which can encode up to hundreds of viral proteins, RNA viruses have smaller genomes that usually encode only a few proteins.
Explanation:
hope it helps my dear friend.
Answer:
Difference Between DNA & RNA Viruses
A virus can self-replicate inside a host cell. ... The viruses that contain DNA as their genetic material are called the DNA viruses. RNA viruses, on the other hand, contain RNA as their genetic material. DNA viruses are mostly double-stranded while RNA viruses are single-stranded
